- Update to version 4.1.0 * collectives: Add HAN and ADAPT adaptive collectives components. Both components are off by default and can be enabled by specifying "mpirun --mca coll_adapt_priority 100 --mca coll_han_priority 100 ...". We intend to enable both by default in Open MPI 5.0. * OMPIO is now the default for MPI-IO on all filesystems, including Lustre (prior to this, ROMIO was the default for Lustre). Many thanks to Mark Dixon for identifying MPI I/O issues and providing access to Lustre systems for testing. * Minor MPI one-sided RDMA performance improvements. * Fix hcoll MPI_SCATTERV with MPI_IN_PLACE. * Add AVX support for MPI collectives. * Updates to mpirun(1) about "slots" and PE=x values. * Fix buffer allocation for large environment variables. Thanks to @zrss for reporting the issue. * Upgrade the embedded OpenPMIx to v3.2.2. * Fix issue with extra-long values in MCA files. Thanks to GitHub user @zrss for bringing the issue to our attention. * UCX: Fix zero-sized datatype transfers. * Fix --cpu-list for non-uniform modes. * Fix issue in PMIx callback caused by missing memory barrier on Arm platforms. * OFI MTL: Various bug fixes. * Fixed issue where MPI_TYPE_CREATE_RESIZED would create a datatype with unexpected extent on oddly-aligned datatypes. * collectives: Adjust default tuning thresholds for many collective algorithms * runtime: fix situation where rank-by argument does not work * Portals4: Clean up error handling corner cases * runtime: Remove --enable-install-libpmix option, which has not worked since it was added OBS-URL: https://build.opensuse.org/request/show/882166 OBS-URL: https://build.opensuse.org/package/show/science:HPC/openmpi4?expand=0&rev=12 |
